Critical Environmental Areas (CEAs) are areas officially designated by counties or municipalities to alert landowners, developers, and regulatory agencies to features of importance or concern during environmental review under the SEQR process. This webinar presented the process of designating CEAs, with recent examples in the Hudson Valley, and will address convening a working group, engaging with and informing landowners within a proposed CEA and the general public, and the step-by-step process of identifying, delineating, describing, and adopting a CEA.

In this field workshop, we discussed the values of small wetlands and streams; how to find and identify them; threats to wetlands and streams; and effective regulatory and non-regulatory protections.

Little Stony Point, part of Hudson Highlands State Park, is a small, rounded “point” that juts out into the Hudson River. It has a nice variety of habitats for such a small area, including mature oak forest, mixed-hardwood forest, a rocky summit (with excellent views), tidal sandy shore, and two dry, sandy meadows, where several interesting species dwell.

Which natural areas are most vital in my community? How do we plan for a future that sustains nature and quality of life for residents? What types of conservation policies have been successful in other communities?

From tidal wetlands to grasslands, large forests, and rocky crests, the Hudson Valley is home to diverse habitats that support abundant fish, wildlife, and plant species, and provide numerous benefits to local communities. Despite comprising just 10% of the state’s land area, the Hudson Valley supports nearly 90 percent of the bird, mammal, reptile, and amphibian species that live in New York. The region is also one of the fastest growing in the state, making conservation of this rich natural heritage even more urgent.
